That looks to be a sensible and sane fix - thanks for catching, reporting and 
fixing this issue!

I'll get a new version out soon with that change.

I'll also see if I can handle Issue 11 at the same time:

To support multiple keys, I think I might need to add an "editing" flag rather 
than just test for the presence of the 'id' field; then, I can add each of the 
key columns to the URL (or perhaps as hidden form fields), use them all in the 
WHERE clause of the update - for e.g., if simple_crud() was called with 
key_column => [qw/key_1 key_2 key_3/], then that section of editing code would 
become something like:

if (params->{simplecrud_mode} eq 'editing') {
    my %where;
    my @key_cols = ref $key_column ? @$key_column : ($key_column);
    for my $key_col (@key_cols) {
        $where{$key_col} = params->{$key_col};

    $success = database->quick_update($table_name, \%where, \%params);
    $verb = 'update';

At a quick glance, a change similar to above should take care of both the 
problem you were seeing, and saberworks' need for composite keys.
